I have a null, with some string parameter. The first is a file directory parameter im using to get file paths and update them quickly.
Is there a way in hscript to take just the last folder name from this string, and generate a new parameter from that?

Example:
directory-- D:/MEGASCANS_LIBRARY/Downloaded/surface/stone_floor_vixidai
extracted string one--stone_floor_vixidai
extracted string two--vixidai



the first part of the string
D:/MEGASCANS_LIBRARY/Downloaded/surface/---will never change. its just that last path.

Thank you!



Ive attached an image which should make it clear.
Thanks!!!

Hscript gives you a handful of path modifiers:

But often its not quite what you need, and by the time you've backticked and text stripped and whatever else, the expression has become an unreadable mess.

Python is usually a better fit for these kind of things.

I know you want to do it in hscript . But i only can do that in python . Hope it helpful with you . 


// in wrangle
s@path = "D:/MEGASCANS_LIBRARY/Downloaded/surface/stone_floor_vixidai";
s@path_01 = "";
s@path_02 = "";


In Python : 
node = hou.pwd()
geo = node.geometry()
path = geo.attribValue("path")[::-1]
path_final = ""
path_final_02 = ""
for element in range(0,len(path)):
    
    if ( (path[element]) != "/" ):
        
        path_final += path[element]
    
    elif ( (path[element]) == "/" ):
        
        break

geo.setGlobalAttribValue("path_01",path_final[::-1])

for element in range(0,len(path_final)):
    
    if ( (path_final[element]) != "_" ):
        
        path_final_02 += path_final[element]
    
    elif ( (path_final[element]) == "_" ):
        
        break 
        
geo.setGlobalAttribValue("path_02",path_final_02[::-1])

I'd go with Python only if it's an expression as mestela suggested

if you go with detail attribs then a single Detail wrangle should be enough:
string path = "D:/MEGASCANS_LIBRARY/Downloaded/surface/stone_floor_vixidai";

splitpath(path, s@dir, s@filename);
s@suffix = split(s@filename, "_")[-1];
